I got a friendly email a while back with a couple of mp3s from a Run DMC Remix project.
Here's part of that note:
"The re-issues contain unreleased bonus tracks such as demos, live performances, single B-sides, and remixes. Also included are all new liner notes from key MCs, producers and celebrities like 50 Cent, Chuck D, DJ Red Alert, Chris Rock, and Eminem along with rare photos and memorabilia and an insert for official Run DMC ringtones."
Here are the free mp3s...
